Résumé

Across the tropics, landscapes of continuous rain forest are being replaced by forest fragments embedded in a matrix of pastures and farmlands. This conversion has endangered many species, including arboreal primates. Species vary, however, in how they are able to supplement their diets from the matrix, although this is rarely studied in primates. We studied two groups of black howlers (Alouatta pigra) for a total of 1156 h, one inhabiting a smaller fragment (0.4 ha) and the other a larger fragment (20 ha). monkeys inhabiting the smaller fragment spent more time in the matrix than in the habitat fragment, spending 50 % of their time (335 of 667 h) in an abandoned mango (Mangifera indica) plantation, 8.8 % in scattered trees, and 0.2 % in pastures. In contrast, monkeys in the larger fragment spent 75 % of their time (368 of 489 h) in the forest fragment and only 25 % of their time in the matrix. Feeding in the matrix accounted for 53 % and 12 % of the foraging time for groups in the smaller and larger fragments respectively. We suggest that Alouatta pigra can use resources in the matrix to supplement their diet by means of crop raiding or taking other resources in many fragmented landscapes and that this may be true also for many fragment-dwelling primates. It is important to include a consideration of the matrix in conservation planning, considering both the total resources available to primates and the consequences of crop raiding for farmers. © 2013 Springer Science+Business Media New York.
